The GNU Scientific Library (GSL) is a C library that has hundreds of functions that are useful to scientists and mathematicians, such as special functions, linear algebra, statistics, etc... Wouldn't it be nice if you could access them all with Perl? Now you can with Math::GSL!

Warning: You are on the bleeding edge, this is alpha code, so if you want to test it out on your platform and report bugs or send patches, then please do! Yes, there is just about no documentation right now. Anyone care to write some?
